    02 Gear

    Gear by level, from 72 hours to months

    Start with the basics and add more once you have them. Tick what you already have and you'll see what's missing.

    03 Know-how

    Skills that don't depend on a battery

    First aid, fire, shelter, knots, navigation and signals, step by step, with illustrations that work offline.

    04 Emergencies

    What to do when it happens

    Clear guides for before, during and after. Print them or keep them on your phone: they work offline.

    Works when nothing else does

    After your first visit, everything works offline. In a blackout, blackout mode turns the screen black and removes animations so the battery lasts longer.

    Where the figures come from

    Latest news

    Prepping, blackouts, cyberattacks, supply problems and emergencies in Spain, Latin America and the rest of the world. Collected automatically every 6 hours.

    Links to outside media. The selection and the country of each story are automatic: always check against official sources.

    Supply calculator

    Tell us who lives at home, how many days you want to cover and any allergies, intolerances or special diets. We work out the water (drinking, cooking and basic hygiene), a shopping list with real weights and the other supplies. Every figure has a source: where the numbers come from.

        Keep in mind

          Estimates per person per day: 2,200 kcal per adult, 1,900 per person over 65, 1,800 per child aged 7 to 13 and 1,300 for ages 3 to 6; babies are counted separately. These are the planning figures of Germany's BLE and the D-A-CH reference values (sources). Adjust them to your health and activity, and check with your doctor if someone is on a prescribed diet. Buy a little at a time, not all at once.

          Pantry: what to buy

          Specific products from any supermarket that keep for months or years unopened without a fridge. You don't need special survival food: buy what you already eat, in these formats, and rotate it. The calculator gives you the quantities.

          My shopping list

          Tap "Add to list" on the products you want to buy.

            Shelf life is a guide for unopened packs kept somewhere cool, dry and dark: the date and instructions on the label always come first. Source on dates: AESAN.

            Inventory and expiry dates

            Write down what you already have stored. We tell you how much you're missing compared with the calculator and what expires soon so you eat it and replace it. It's only saved on this device.

                What battery and solar panel do I need?

                Tick the devices you want to keep running without power and how many you have. We tell you how much battery you need to last the days you choose and which solar panel recharges it each day.

                Survival skills

                Knowledge weighs nothing, never expires and can't be stolen. Read these now and practice them: in an emergency there's no time to learn.

                Fitness for emergencies

                In an emergency your body is your first tool. No gym or equipment: just a chair, a few water jugs and your bag. Your log is only saved on this device.

                      Morse code

                      To call for help or communicate without a voice or signal: with a flashlight, a whistle, knocks or your phone screen. Works offline.

                      SOS is sent run together, with no gap between letters, and repeats. With "Light", the whole screen flashes (at most 2.5 times per second): tap it or press Esc to stop. If you or anyone nearby has photosensitive epilepsy, use sound or vibration. It drains the battery: use it when someone can see you.

                      Dots and dashes; one space between letters and "/" between words.

                      Timing

                      • · dot = 1 unit
                      • — dash = 3 units
                      • between signals in a letter = 1
                      • between letters = 3
                      • between words = 7

                      Drinking water

                          Offline maps and navigation

                          With no data or signal you can still know where you are and where to go, if you prepare beforehand.

                                • Location: GPS is only read when you tap a button that asks for it, and the browser asks for your permission.
                                • External links: the news, the sources and the shopping links lead to other websites, which have their own privacy policies.
